Coffman said his son, who was about to join the Army, hasn’t answered his phone.

By 3:40 a.m., he arrived at the Thousand Oaks Teen Center to search for him and report him missing.

He emerged about 15 minutes later. Authorities inside took down his information and told him to wait for word.

His next stop, he said, was the hospital.

Early Thursday morning, Los Robles Regional Medical Center was quiet.

A sheriff’s department crime scene investigations van pulled up to the hospital just before 3 a.m. An hour later, a law enforcement official in an honor guard uniform was seen leaving.

Adam Housley, who until six weeks ago was national correspondent for Fox News, arrived at the hospital around 3:30 a.m. searching for his niece. A guard didn’t let him through, saying it was on lockdown.

He said his niece, 18-year-old Pepperdine freshman Alaina Housley, had been at the bar with several friends. Her Apple Watch and iPhone still showed her location on the dance floor.

Housley said two of Alaina’s suitemates jumped through a broken window to escape and are at a hospital with major wounds from the glass. As they ran away from the bar, someone screamed “Hey! Get ... down on the ground!” They told Housley they believe it was the gunman.
